南京市轻型车行驶工况的研究

Research on Driving Cycle of Light Vehicle in Nanjing

通过对南京市主城区道路网进行研究分析,对道路进行分类,选择典型道路采集交通流量以及道路状况的调查分析,采用GPS定位技术,实时记录了南京市实际道路状况下轻型车的运行状况,通过对从GPS轨迹记录仪中获取的大量速度数据的分析处理,合成了南京市轻型车的综合行驶工况,并与标准测试工况、主要城市工况进行了对比分析,指出了南京城市轻型车运行的特点。

Road traffic and conditions in Nanjing are surveyed in which road conditions are classified, and real-time record of light-vehicle＇s working conditions on roads is made using GPS positioning technology. Speed data from GPS trajectory recorder is analyzed, which gives a goneral picture of driving cycle in Nanjing. By a comparative study with standard test conditions, and conditions in other cities, features of operation of vehicles are pointed out.
